I never said that meat was not available for all of human history or that prehistoric humans did not consume meat. I'm talking about the (low quality) quantities available to almost anyone almost anywhere in the world for a relatively low price. And from looking at developing economies, it seems increased consumption of meat is an intentional sign of increasing wealth. As far as large scale domesticated animal production, that is a "relatively" new thing. Before modern transportation, there were many parts of the world where such meat was minimal or simply not available.
